drape image dataset onto DEM surface in ArcGlobe?

larryzhang

Hi, all,

We added two raster dataset (image & DEM) into ArcGlobe 10, and expected that the image dataset should be smoothly draped on DEM or DEM surface in 3D. In fact, it wouldn�??t work, which is always flat floating on DEM. Missing anything?

However, we use those raster datasets in other non-ESRI application server and can easily get it in the client (see the attached snapshot, which was perfectly draped onto DEM).

What about image service onto DEM image service from Mosaic Dataset? It looks not working either in ArcGlobe.

Intentionally, we wanted that image services can be draped onto DEM image service in ArcGlobe, and served again as a globe service. Those image services are from Mosaic Dataset and served in ArcGIS Server 10 (image ext).

Thanks for your valuable instructions, Eric,

On the combination of your advices, it is working fine for us right now, including our very-high-resolution DEM & image services from MD.

In next step, we will follow the documentation to improve the globe services and see if we can make them faster.

Larry, 

The hillshade effect shouldn't do anything if your surface appears too flat. You may need to set an exaggeration (like you mentioned for GE) in ArcGlobe. Go to View > Globe Properties and set it for the surface. You may also want to go to Customize > ArcGlobe Options and turn up the   Level of Detail for Elevation layers. We don't show the full LOD to increase performance. My screenshots below are from the coordinates you gave me. I have no exaggeration applied, but high detail for elevation. When I exaggerate to 1.5 I don't like the appearence, but that could be just me.

By the way, most of our users like the factor 2, which makes the globe services in this continent look more realistic.
